BaseAdapter containing TextureView and MediaPlayer doesn't work

Question

What I'm trying to do is to populate a ListView with a BaseAdapter which has a TextureView in it. The problem is i don't see any video playing before waiting at least 2 mins, and its not about my internet connection speed. When i set the width of TextureView to 300dp, my ListView starts containing more than one view and all of the views start playing the video creating a chaos. I want my program to work like Vime or Instapram applications, auto-starting when it has focus(or visible), and pause when i scroll. I had an 5 hours of search in web and still nothing. Any guide, help, sample code will be appreciated. Thanks in advance.

public class VideoAdapter extends BaseAdapter {
private Activity context;
private ArrayList<String> urls;
private MediaPlayer mediaPlayer;

public VideoAdapter(Activity context, ArrayList<String> urls) {
    this.context = context;
    this.urls = urls;

}

@Override
public int getCount() {
    return urls.size();
}

@Override
public Object getItem(int position) {
    return urls.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int positionx, View convertView, ViewGroup parent) {
    final ViewHolderItems viewHolderItems;
    SurfaceHolder surfaceHolder;
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if (convertView == null) {
        convertView = inflater.inflate(R.layout.single_video_item, parent, false);
        viewHolderItems = new ViewHolderItems();
        viewHolderItems.textureView = (TextureView) convertView.findViewById(R.id.textureView);
        convertView.setTag(viewHolderItems);
    }else{
        viewHolderItems = (ViewHolderItems) convertView.getTag();
    }
    final int position = positionx;
    LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)viewHolderItems.textureView.getLayoutParams();
    params.height = 850;
    params.width = LinearLayout.LayoutParams.MATCH_PARENT;
    viewHolderItems.textureView.setLayoutParams(params);
    mediaPlayer = new MediaPlayer();
    viewHolderItems.textureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
        @Override
        public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
            mediaPlayer.setSurface(new Surface(surface));
            mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
            try {
                mediaPlayer.setDataSource(urls.get(position));
                Log.d("JWP", "" + urls.get(position));
                mediaPlayer.prepareAsync();
                mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mp.start();
                    }
                });
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {

        }

        @Override
        public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
            /*mediaPlayer.stop();
            mediaPlayer.release();*/
            return false;
        }

        @Override
        public void onSurfaceTextureUpdated(SurfaceTexture surface) {
        }
    });

    return convertView;
}
static class ViewHolderItems{
    TextureView textureView;
}
}

I don't have any crashes, but errors still come up:
